Abstract
High-capacity pick-up mechanisms operable for selectively reading data from and/or writing data to one or more surfaces of one or more optical storage media are disclosed. These mechanisms comprise a first pivotable structure, a second pivotable structure, a first reflective element, a second reflective element, a light source, and a light receiving device. The light source and the light receiving device are remotely located from the reflective elements via the pivotable structures, and only the reflective elements and a portion of the pivotable structure are positioned adjacent the surface of an optical storage medium. High-capacity optical read/write devices and systems comprising these high-capacity pick-up mechanisms are also disclosed.
